I have to say that it has become almost impossible to discuss anything about Video Games on Lemmy. If you mention a Video Game made by Nintendo, and that you like it -> Stop supporting Nintendo, they are bad. If you mention a Denuvo Game, and that you like it -> Stop supporting them, they are bad. You have a Problem with a game -> switch to Linux and it will fix all your problems.
And you should buy a steam deck, because GabeN and getting people addicted on gambling is cool. We're not being hypocritical here.
If you have a server to Self Host stuff, you can also use Gamevault. It's like steam but Selfhost. You can Backup your Save Files onto your Server (you need to modify the Open Source Client for that, otherwise it's behind a Paywall.) It tracks your Playtime. You can install .7zip files, iso's and gog games very simple. You can also see what your friends are playing, if you share your Server.
I also love it to collect fan games in it like PokeMMO, Mario 64 PC Port etc.
